SPECIFICATION forming part of Letters Patent No. 529,636, dated November 20, 1894.-

Application filed July 26, 1893- Serial No. 11 9 (N0 model.)

To all whom it may concern: 7

Be it known that I, Euenrn TYMESON, a citizen of the United States, residing at Yonkers, county of Westchester, and State of N ew York, have invented certain new and useful Improvements in Moquette-Looms, fully described and represented in the'followingspecie fication and the accompanying drawings, forming a part of the same.

The invention is of general application in power looms for weaving tufted fabrics, but is especially designed for use in looms for weaving moquette carpets, and will be illustrated and'described in connection therewith..

One feature of the present invention consists in the general construction and arrangement of the loom bywhich a row of tufts is inserted to each two shots of filling. one shot of filling passing through the row of tufts and forming a holding weft and the other binding the row of tufts upon the holding weft and forming a binding weft. By thus inserting two shots of filling to each row of tufts, instead of three or more as previously in this class of looms, it is evident thata much higher capacity may be secured, one of the features limiting the capacity of such looms previously in use being the time required for inserting the larger number of shots used in the filling.

In looms of one of the common forms, the tuft spools are carried by a pair of chains or an equivalent spool carrier, which is advanced step by step to bring the successive tuftspools into position for use, and these tuft spools are successively removed from the carrier for I the insertion of a row of tufts therefrom and returned to the carrier afterthe row hasbeen inserted. The tuft spools are commonly carried between thespool carrier and the position of use by transferring arms taking and returning the spool at the same point, the movement of the carrier to advance the next spool into position to be taken by the transferring arms taking place after the previous spool has been returned to the carrier; Y

I provide an improved tuft spool movement, increasing the capacity of looms employing a spool carrier from which the spools are removed for inserting the tufts, by advancing the spool carrier during the movement of the transferring arms and between the operations of taking and returning a spool, and changing the relative positions of the spool carrier support and transferring arms for returning the spool and taking the nextspool. This change of relative position is secured preferably by moving the spool carrier, support, and when, as is preferable, the spool carrier consists of a pair of chains in successive links of which the spools are carried, the chain wheel next the transferring arms is preferably mounted in a swinging support which is actuated by suitable means so as to reciprocate the lower end of the chains in the line of movement of the chains in proper time to secure the result desired. By this construction, it is evident that more than two shotsof filling are used to each row of-tuft-s, it is evident that these two features co-act to sccu re a very high capacity, and the invention consistsin part in their combination, the insertion of but two shots of filling to each row of tufts reducing largely the time required for the formation of the bodyof the fabric, and the specialspool movement permitting the attainment of this high capacity in looms of that special class in which the tuft spools are removed from the carrier.

The invention includes also certain specific I features of construction and combinations of parts, all of which will be'fully described hereinafter and specifically pointed out in the claims.

For a full understanding of the invention, a detailed description of a loom embodying the same will now be given in connection with the accompanying drawings forming a part of this specification, which shows all the feattures of the invention embodied in the preferred form in a loom of a common type.

In the drawings:Figure 1 is a side elevation of theloom, and Figs. 1 and 1 are detail views showing the inside heddle cams in correct positions. Fig. 2 is a side elevation of the opposite side of the loom omitting the warp rolls. Fig. 3 is a vertical section on the line 3 of Figs. 1 and 2. Fig. ais a horizontal section on the line L of Figs. 1 and 3, parts being omitted to show the transferring arms. Fig. 5 is a horizontal section on the line 5 of Fig. 3, showing especially the needle mechanism. Fig. 6 is a vertical longitudinal section on the line 6 of Fig. 3. Figs. 7 and 8 are similar partial sections showing the parts in difierent positions. Figs. 9 to 13 show the tuft carrier mechanism in different positions. Figs. 14 to 17 are details of the spool gripping action in the position shown in Fig. 13, Fig. 14: being a side view of one end of the transferring arms and a spool carriage. Fig. 15 is a horizontal section on the line 15 of Fig. 14, and Figs. 16 and 17 cross sections on the lines 16 and 17 of Figs. 14 and 15. Fig. 18 is a section similar to Fi 17 showing the parts in position with the spool gripped by the transferring arms. Fig. 19 shows the product in plan with the tufts removed, and in longitudinal and cross section.

The loom shown is as to its general character, similar to those in common use for weaving tufted fabrics, and shown in many prior Letters Patent, for instance, Nos. 1 6,037, 186,374, 233,290 and 233,291, and as the construction and operation of such looms are well understood, it will be described only so far as is necessary in connection with the illustration and description of the invention forming the subject-matter of the present application.

A is the frame of the loom in which is mounted at the rear end the warp rolls I5, 0, from which the warps weighted by weights X are led to the heddles in the usual manner. Three heddles are employed, lettered respectively D, D D these heddles carrying the warps as usual in such constructions, and the fabric passes from the weaving mechanism over the breast beam E to the winding up rolls F. The warps are arranged in series'of four transversely to the fabric as usual in such constructions, and any common or suitable heddle and weft carrier movement may be used, but the relative operation of these movements differs from that in looms previously in use so as to open and close the warp and insert the weft as will be fully described hereinafter.

1n the construction shown,theheddlesDand Dcarry one each of the binder warps and the heddle D carries the dividing warps of each set of four. The heddles D, DD are actuated from their respective cams d, d d through levers 11, connecting rods 12, levers 13, and links 14, the cams being carried by a sleeve loose on the main shaft bl and driven therefrom at one half the speed of the shaft by gears 15, the main shaft S being driven from driving shaft T by gears 16.

The tuft spools 11 having the usual carriages I'and tins 17 for inserting the tufts are carried by a pair of chains J, forming the spool carrier, as usual in such constructions,

and the tuft spools are transferred from the chains to the warp for the insertion of the successive rows of tufts and returned to the carrier J, by transferring arms K carried by supports N pivoted to the frame of the machine to swing in a vertical plane and carry the transferring arms between the spool carrier and warp, the arms K being pivoted to the supports at 41 so as to swing horizontally toward and from each other to seize and release the spools. In previous constructions, the chains J have been stationary from the time that a spool was taken by the transferring arms until it was returned to the chains, as the link must lie in the same position when the spool is taken and returned by the transferring arms.

The present invention provides an improved construction by which the chainsmay be advanced to bring the next spool into position to be taken by the transferring arms whilea spool is out of the chains, the correct relative position of the arms and chains for the return of the spool being secured by returning the chains by a movement of such acharacter as to increase materially the rate of speed at which the loom may be operated. In the construction shown, the lower sprocket Wheels 18, of which two are used, instead of being mounted in a fixed part of the machine, as usual,are mounted in a movable support consisting in the form shown of aframe G pivoted to swing to and fro in the line of movement of the chains and stopped in each direction by adjustable stops 6. This support G is carried by a rock shaft l9 which is actuated by cam r gn shaftfiWt-hrough lever 20, link 21 and crank arm 22 on shaft 19 at one side of the loom. The chain is advanced to bring the successive spools into position for the transferring arms by the usual means, consisting of a ratchet 23 on the shaft of one of the sprocket wheels 18, this ratchet being advanced by a lever L carrying a spring pressed pawl 24 and operated by a cam Zon the shafnS. through lever 25 and link 26. For the purpose of holding the chain stationary during the swinging of the support G so as to prevent the shifting of the spools, I preferably use a stop ratchet 27 on the same sprocket wheel shaft, this ratchet being engaged by a stop pawl lever M carrying two pawls (Fig. by which the sprocket wheel is held against motion in either direction, this stop pawlleverM being rocked at the proper time to permit the feeding movement of the chains by a lever 28 pivoted on the frame and actuated by a camnnt on shaftS through lever 29 and link 30. This stop pawl M is shown in Fig. 2 in its normal position holding the sprocket wheel 18 through ratchet 27 engaged IIO by its pawls against movement in either direction, so that the chains are positively held against movement during the swinging of the support G and at all times except when this stop pawl lever is raised, when it is necessary to permit the rotation of the sprocket Wheel 18 for the feeding movement ofthe chains.

The transferring arms 'K are swung with the supports N in a vertical plane to carry the spool between the chains and warp by earns at each side of the loom, acting through levers 31 and links 32. The spool carriages are rocked for the insertion of the tufts from cams it at each side of the loom through levers 31' pivoted on levers 31, links 33, bell crank levers 34 mounted on a spring pressed shaft 34 and links 35, and the transferring arms are rocked in a horizontal plane on the supports N to seize the spools by a vertically sliding bar 36 carrying a cam p whichengages a projection on the side of one of the arms K, this bar 36 beingactuated by a cam 70 on shaflLS through lever 37, the two transferring arms being connected so as to move in opposite directions by a lever 38 and returned to positionto release the spools by aspring 39 connected to the lever, all substantially as in the patents above referred to.

The spool carriages are shown as. hung in the chains in substantially the same manner as in Patent No. 186,3Z4 and the transferring arms are provided with substantially the same grip for seizing the carriage and releasing it from the chains but the construction of the devices coacting with the grip in taking-and returning the spool are varied. These grips preferably seize the spool carriage on each side so as to hold the carriage and spool in proper position and prevent its accidental rocking. it is necessary, therefore, that the spool and spool carriage be held in accurate.

position in the chains to be taken by the transferring arms and it is desirable, also, that means should be provided by which the spool carriage is raisedbefore the grip seizes the carriage so as to relieve the pressure on the catch and is supported and forced upward into the chainswhen released by the grips, so as to assure the proper action of the catch. In constructions previously in use, fingers or similar devices mounted in fixed position on the frame have been used for this purpose, but this is not entirely satisfactory, especially with my improved construction employing the movable chain support,

as for high speed it is desirable thatsuch devices be so constructed as to aid-in the return of one of the spools to the chains and to act on the next spool during the shifting of the spool carrier support so that the grips on the transferring arms may take the spool at once on' the shifting of the support, avoiding the loss of time which is required to position the carriage if allowed to swing freely during the movement of the support, the transferring arms preferably being held stationary during the movement of the chain support and the grips being simply moved in to grip the spool carriage as the carrier support is shifted.

I provide an improved construction, in which the devices co-acting with the grips in taking and returninga spool to the chains are carried by the transferring arms, these devices preferably being so constructed as to allow the support and chains to move over the transferring arms while the latter are stationary'in the upper position, and co-act with the grip in returning the spool previously taken by the transferring arms, and to hold the next spool in proper position during the swinging of thesupport so as to be taken at once when the support is shifted. The construction is shown particularly in Figs. 4, 6, 12, and 13, and the detail views Figs. 14 to 17.

The grips shown have the usual three fixed arms 1 in which the spool carriage rests and the spring pressed arms 2 which are pressed against the spool to hold the latter against accidental turning, and the spool carriage has the usual catch spring3 passing inside the chain link and released by the grips when the latter are pressed inward against them and the arms 4 passing through the link, this arm being bent outwardly from the catch spring so as to form a shoulder below the link. It will be understood, however, that the form of these grips may be varied. The improved means coacting with the grips are as fol lows:

A flat spring 40 lying above each transferring arm is secured in a fixed position relatively to the sidewise movement of the transferring arms K, and may be carried by the vertical pivots 41 of the transferring arms, as shown, andsecuredin a fixed position thereon by any suitable means. These springs extend to the end of the transferring arms above the grips and rest normally on top of the grips and so as to be brought just below the shoulders on the spoolcarriages formed by the arms 4 when the grips are raised by the arms into their upper'position to take a spool; the springs is provided with a side arm 5 curved over the transferring arms so as to form a earn as shown in Fig. 16, sothat the transferring arms raise the springs when the arms are rocked outwardly and the springs are released and lowered when the arms are rocked inwardly.

The operation of the construction will be the machine.

The lay O is carried by arms 42 on a rock shaft 43 actuated by cam o-on shaftb through lever 44 and link 45 and controlled by stop 46. The comb P is carried by arms 47 pivoted on crank arms 48 on rock shaft 49, the shaft being spring pressed in one direction p on shaft S- through lever 50, link 51 and crank arm 52 on shaft 49, and the comb is raised and lowered by link 53 pivoted thereto described in connection with the operation of and actuated in theopposite direction by cam Each of g and connected to one arm of the bell crank lever 54, returned by spring and actuated against the tension of the spring by a cam p on shaft S through lever 56 and link 57 connected to the other arm of p the bell crank. The comb P is controlled by an adjustable stop 58. A pair of horizontally moving cut-- ting blades are used for severing the tufts, the front cutting blade Q being carried by arms 59 mounted on rock shaft 60 and actuated by cam on shaft S through lever 61, which is pivoted on thefrarne at 86 connected to crank arm 62 on the shaft 60 by link 87 and the other blade Q slides in guides 63 and is actuated by cams ion shaft S through levers 64 and links 65 at each side of the loom. It will be understood, however, that these parts in themselves form no part of the present invention and that other means may be used for trimming otf the tufts and beating up the body of the fabric,such devices being readily varied by those skilled in the art.

Any suitable means may be used for inserts ing the shots of filling, such as any of the means shown in the patents above referred to. In the drawings, however, I have shown a common construction employing a selvage shuttle and needle, which will be found simple and etlicient. In this construction the needle R. carrying the thread is actuated from a cam mu the shaftfi through lever 66, link 67, lever (-38 and link 69, so that a very quick movement of the needle is secured. The thread is carried through the fixed guides and is drawn 0d the spool by a take up U which is rocked to draw oif the thread and returned to position by a cam disk to on the shaft S carrying two cam projections acting through lever 71, link 72 and arm 73 on thesleeve carrying the take up U. The thread is caught on the needle side of the loom so as to be held until the warp has been shifted and the next shot is being made by a catch 0 carried by a bar 84 pivoted at by a slotted pivotal connection so as to be free to slide vertically and provided with an inclined slot I 7 in which engages a bowl carried by a lever 74 which is actuated by cam an on shaft .8 through lever 75 and link 76, a rod 8 being pivoted to the sliding bar 84: carrying the catch 0 and moving in a bearing in frame A, sufficient friction being provided in this bearing to secure the proper up and down movement of the catch as the bar 84 is moved up ward and downward by the movement of the bowl on the lever 74. in the inclined slot 7. At the opposite side of the loom is mounted in a curved race 77 a shuttle V carried by a swinging arm 78 so as to be oscillated for making the selvage in the usual manner, this arm 78 being carried bya vertical rock shaft 79 spring pressed in one direction and actuated in the opposite direction against the tension of the spring by ca nnton shafgfi through lever 80, bell crank 81 and link 82 connected to crank arm 83 on the shaft.

The operation of the loom will be under- 'stood from a brief description of its general features without a detailed description of the operation of the various parts, except so far as the latter are new and in themselves form parts of the invention, as the operation of the parts of the mechanism in detail is substantially the same as in looms of this class heretofore in use and will be clear to those skilled in the art.

The operation will be more readily understood from a brief description of the fabric in connection with Fig. 19, in which the body of the fabric is shown open to separate the threads for the purpose of illustration, it being understood,however, that in practice the filling is beaten up by the lay of the loom, so as to force the filling and tufts together and make a solid fabric.

The warps are arranged in sets of four at short intervals apart across the fabric as usual in such constructions, but only two wefts are used to each row of tufts. Two of each set of four warps form the dividing warps, and lie between the upper and lower wefts of each pair, and the other two of each set of four warps form the binding warps and pass alternately above and below the wefts of each pair so as to bind them and the dividing warps together. of the two shots of filling for each row of tufts, one shot passes through each row and forms the holding shot, and the other binds the row on the holding shot and forms the bindin g shot. In the construction illustrated, the outside warps of each set of four are used as the dividing warps, and the inner warps as the binding warps, although it will be u nderstood that this arrangement is not absolutely essential, and for convenience of description the warps are numbered is series, the dividing warps being lettered a", 00 and the binding warps 00 w, and the holding and binding wefts are lettered respectivelyy, y. The arrow in Fig. 19 shows the direction of movement of the warp in weaving.

The position in which the parts are shown in the general views, Figs. 1 to 6 and Fig. 9, is thatin which a row of tufts and pair of wefts have been inserted, the spool has been returned to the carrier and another spool has just been taken by the transferring arms K and is about to be lowered for the insertion of another row of tufts. In this position of the parts, heddles D and D carrying respectively binding warp m and dividing warps 00', m are raised, and heddle D carrying binding warp m is lowered and the lay O is just about to beat up and the warps to be shifted into central position. The binding weft 3 having been beaten up by the lay and the warps shifted, the transferring arms K descend with the spool, and the ends of the tuft material are inserted behind the previous row of tufts and pair of wefts, and the heddles are then shifted so as to raise heddle D and binding warp m but to lower heddle D and dividing warps w, m with heddle D and binding warp The needle R is then actuated to insert the upper or holding weft y, the lay beats it up, and the transferring arms are raised slightly to draw off the tufts, this position of the parts before the return of the heddles to central position'being shown in Fig. 7. As the needle is inserted and Withdrawn the shuttle V passes the selvage thread through the loop of the weft and the catch 0 is raised and lowered in proper time so as to hold the loop until the warp is again shifted, each weft, in this construction, therefore, being doubled. The heddles are now shifted into central position and the lay 0 being withdrawn the comb P is actuated to carry up the ends of the tufts around the holding weft, as usual in such constructions. Y The heddles are now shifted again to open the warp, heddle D and binding warp m being lowered and heddles D, D carrying binding warp m and dividing warps as, m raised, when the needle is again actuated to insert the binding weft y, and the'tufts are cut off by the cutters Q, Q, this position of the parts being shown in Fig. 8. The lay 0 now beats up the binding weft, the transferring armsare raised to return the spool and take the next spool and the cutters return to normal position. The operation is exactly the same for the'next row of tufts except that the shifting of the binding warps is reversed, heddle D7 and binding warp 00 being raised and heddle'D and binding warp m lowered on the first shot, and heddle D raised and heddle D lowered on the second shot, as will be apparent from an examination of Fig. 19, showing the fabric, this re- Versing being preferable on account of the position of the binding warps after the insertion of the binding wefts.

During the movement of the transferring arms K with the spool, the chains J were advanced by the pawl arm L and ratchet 23 to bring the next spool into position to be taken by the transferring arms, the arm M carrying the stop pawls being raised at this time so as to permit the rotation of the sprocket Wheel 18 engaged thereby, and being returned to position as soon as the chains have been advanced so as to hold the chains against accidental movement in either direction. It is necessary, however, that the link from which the spool was taken by the transferring arms be in proper position to receive the spool from the transferring arms, and to secure this result the carrier support G is shifted just as the transferring arms are about to return the spool so as to return the link to proper position, and then, immediately upon receipt of the spool the carrier support swung forward again to .bring the next spool into position to be taken by the transferring arms, the movementin either direction of the chain on the sprocket wheel duringthe swinging of the carrier support being prevented-by the stop pawls on arm M engaging the stop ratchet 27 and locking against rotation the sprocket wheel 18 carrying the ratchet 27.

The movement of the spool carrier and swinging support will be clear from Figs. 6'

to S and 9 to 13. In Figs. 6 and 9, in which the transferring arms are just aboutto take a spool from the chain, the swinging chain support is in its normal position, and the pawl lever L is in its upper position ready to advance the chain. In Figs. 7 and 10 the spool has been withdrawn from the chains by the transferring arms, and the pawl lever L has been actuated to advance the chains so as to bring the next spool into position to be taken by the transferring arms, the link J from which the spool carried by the arms was taken being new between the two sprocket wheels 18 by which it is held 'in horizontal position ready to receive the spool. In Figs. 8 and 11 the carrier support G has been rocked rearward so as to bring the link J'for the spool carried by the transferring arms over the transferring arms, and in proper position to receive the spool upon the return of the latter.

The action of the grips on the transferring arms and the springs 40 is as followsz-As the transferring arms are raisedfor the'return of the spool to the link, the ends of the springs 40 are brought beneath the shoulders formed by the arms 4 on the spool carriage, the arms K being then held in their inner positions gripping the spool carriage by the cam 11 engaging the side of oneof the arms K. The spool carriage having been thus broughtinto position to be taken by the chains, thegarms K are released by the cam n and the spring 39 acting through lever 38 throws the arms outward and the grips release the spool carriage. As the transferring arms are thus moved outward on their pivots 41, they raise the springs 40 by engagement with the cams 5 and the springs are thus pressed against springs 3 as the spool carriages are released by the grips. This position of the parts is shown in Fig. 12, the grips having just been moved outwardly to release the spool carriage and the spring 40 being shown in its upper position pressing the spool carriage catches into the chains. The spool carriage having been returned to the chains, the support G is rocked from the position shown in Fig. 12 to the position shown in Fig. 13, so as to bring the. next spool into position tobe taken by the transferring arms, the springs 40 remaining in their upper position during this movement, and holding the next spool in position to be taken by the transferring arms. As soon as the support has been thus moved into the position shown in Fig. 13, so as to bring thenext spool into position to be taken by the transferring arms, the spool carriage being held in proper central position and rocking prevented by the springs 40, and the carriage being raised thereby so as to relieve the weight on the catch springs 3, the transferring .arms are rocked inwardly against the tension of spring 39 by the cam n the catch springs pressed inwardly by the grips and the next spool car riage gripped, the springs 40 returning to their lower position as the inward movement of the transferring arms relieves cams 5. Figs. 14 to 17 show in detail the position of the parts corresponding to Fig. 13, and Fig. 18 the position corresponding to Fig. 6, with the spool carriage gripped. The parts have now been returned to the position shown in Fig. 6, the next spool carriage having been gripped by the transferring arms and the latter being about to descend for the insertion of the next row of tufts.

It will be found that the improved loom is capable of operation at a very high rate of speed, the use of the two shots of filling for each row of tufts increasing largely the capacity of the loom and this very high capacity being made attainable by the use of the movable support for the spool carrier. As above stated, however, these two features form in themselves parts of the invention independently of their combination and either may be used in looms not employing the other.

It is obvious that the improved construction of devices co-acting with the grips in taking and returning a spool may be used without the movable support, but it is of especial value in combination therewith, as pointed out above.

It will be understood that the construction of the other parts of the loom co-acting with the features especially embodying the invention may be varied widely and that the form shown has been selected only for the purpose of illustration and as a convenient construction of high capacity loom. It will be understood also, that I am not to be limited to the special form or arrangement of the spool movement shown as embodying this part of the invention, but that this construction may be varied widely without departing therefrom. Thus, while it is preferable that the spool carrier support should be shifted relatively to the transferring arms, as this will be found the simplest and most efficient construction, it will be understood that the relative positions of these two parts may be varied for the return of the spool in any other suitable manner.
